BAFFLE PLATE FOR FLUES OF BOILERS.

SPECIFICATION forming part of Letters Patent No. 324,552, dated August18, 1885.

Application filed January 9, 1885. (N0 model.) Patented in England May27, 188 !,Xo. 8,265.

To all whom it may concern.-

Be it known that I, ROBERT GOSLING, of Hatton Court, Ipswich, in thecounty of Suffolk, England, engineer, have invented new and usefulImprovements in Fire-Proof Disks or Baffle-Plates for Use in the Fluesof Steam- Boilers, (for which I have applied for Letters Patent in GreatBritain on the 27th day of May, 1884, No. 8,265,) of which the followingis a specification.

This invention relates to improvements in fire-proof disks orbaffle-plates for use in the flues of stationary, marine, or otherhorizontallyfined boilers for the purpose of economizing fuel andutilizing the heat passing in the flue inside the boiler, and therebycausing the whole interior surface of the boilerflne to become anefficient heating surface.

For this purpose I use a disk mainly composed of ganister material,fire-clay, and silica, compounded in such well-known manner as toproduce a good refractory'material to stand heat Without cracking; or Ican use other refractory material to construct my disks suitable for thepurpose. For use in the fines of stationary boilers I divide the diskinto segments, so that they can be placed or fixed in the fine of theboiler with greater ease, each segment interlocking with key or dovetailor like attachment. The disk rests upon brackets or feet composed of thesame or a like refractory material, and placed at right angles to thedisk, in each of which is cut a slot or groove to better hold the disk.For fitting the disks into the fines of steam-boilers they are placedadvantageously about three feet apart, and with each disk seteccentrically with the axis of the fiuesay, for instance, the top of thedisk about two inches from the top of the fine and the bottom of thedisk about seven inches from the bottom of the flue. Of course the sizeand spacing of the disks must depend on the size of the flue.

In the accompanying drawings, Figure 1 shows a section of a line such asis used in a Lancashire or Cornish boiler; Fig. 2, side View of a disk.7

A is the fine; B B B sections or segments of the disk. B, thelowersegment, has a dovctail or plain groove, G, in the same. The uppersections, B B, have respectively a tongue or key, D, in the one to fit adovetail or plain groove in the other, while a tongue or key, E, fitsthe dovetail or plain groove 0 in the section B; or I may instead makethe disk in more sections for large disks, or in two pieces for smalldisks. The whole disk fits into feet or brackets F, as shown, the saidbrackets or feet being at right angles to the disk, which fits a grooveor grooves in the brackets or feet.

For marine boilers I may make the disks and feet in one piece, and witha boss or projection on the top to abut on the flue, and furnish thefeet or brackets and boss with grooves to fit on iron lugs riveted inthe fine, so as to steady the whole in case of a ship pitching orrolling. Fig. 3 shows this, B being the disk, F the feet, H the boss, Ithe lugs in the flue.

By using disks placed eccentrically with the axis of the flue, therising currents of heat are baffled in their attempt to escape over andround the same, and a great deal of heat thus prevented from beingwasted.

In place of wholly constructing the disks and feet of refractorymaterial, the same may be used on a metal core or backing. When made insegments, such disks are readily adapted for transit from the factory tothe boilers where they are to be set up.

I claim A fire-proof disk or baffle-plate for use in the fines ofsteamboilers, placed eccentrically with regard to the axis of the fine,the same having a boss or abutment to rest against the top of the flue,and being supported on refractory feet or brackets, substantially asdescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 24th day of December, 1884;

ROBERT GOSLING.
